The role of concrete admixture in construction

In the construction of small concrete pump, concrete admixture is added to the concrete when it is transported. On the one hand, the concrete is pumped more smoothly and faster, and at the same time, it can prevent the concrete from deteriorating in the special construction environment. At present, admixtures are commonly used in urban construction. Because there are no strict requirements for concrete quality and pumping in rural construction, the use of admixtures is less.

During the construction of concrete pump in summer, the temperature of mixing concrete is usually high, so the hydration speed and moisture evaporation of cement are generally faster, which leads to a large slump loss of concrete. At this time, we can use the technology of high-efficiency water reducing agent and calcium sugar retarder to adjust the setting and hardening speed of concrete, and effectively control the loss of concrete slump.

In addition, in the construction of large volume concrete buildings such as shear walls, the addition of calcium and sugar retarder can slow down the hydration heat, accelerate the dissipation of heat, reduce the temperature rise in concrete, and avoid the occurrence of temperature cracks.
